I have a late 70's early 80's model 3406A engine, coming out of a 74 International cabover, but supposedly not original truck. Seems to be a good sound running engine. I purchased and drove it home without any issues. I purchased as a donor truck for the transmission and don't need the engine. Starter was weak add went bad the day I purchased the truck, so has a brand new starter in it.The engine will be left in the truck till some buys it so they can hear it run for them self, but I can text a video of it running as well. Call or text (605)77zero-4two82
